The ignition system provides a spark to ignite the fuel/air mixture; it has changed vastly over the years in both the complexity, materials used and method of control.

Magnetos were used on the early engines to create a spark to ignite the fuel, these were eventually replaced by the “distributor, coil, points and condenser system” which is still found on most of the entry level cars of today. More expensive cars have individual coils for each cylinder.

An ignition cable which is also called a spark plug cable or spark plug wire, is situated on the top of the engine and leads from the distributor to its respective sparkplug. The spark plug is situated at a very hot spot in the cylinder head and sometimes very close to the exhaust pipes. There is also heat being passed up through the spark plug itself and as it is being heated by the air/fuel mixture being burnt in the engine and radiated heat from the exhaust pipes.

The Ignition lead transfers electricity from the distributor to the ignition coil or to the spark plugs, with each spark plug having its own lead. Any wire could be used as an ignition cable, as electricity will travel down any conductor, however an ideal cable would meet the OEM requirements. Most reputable cables are manufactured to DIN ISO3808 which specifies the thermal grades and construction of the basic cable quality classes, methods of testing and approval of the cable. Silicon is the best conductor, being able to withstand heat of 220-250 degrees celcius, but carbon and Kevlar can also be used.
